The Development of an Active Noise Control System for a Small Axial Fan

by

Kent L. Gee and Dr. Scott D. Sommerfeldt, Physics and Astronomy Axial cooling fans used in computers, projectors, and printers often contribute significantly to background noise levels in both the workplace and classroom because of the distinct and often annoying tones they produce. These tones are principally caused by spatially unsteady flow through the fan, […]

A Search for an Internal Ribosomal Entry Site in the Human Angiotensin 2, Type 1 Receptor

by

Joseph A. Garcia and Dr. Terry S. Elton, Chemistry and Biochemistry The study of human genetics has recently exploded into numerous fields and, as a result, our knowledge of genetics and gene related illnesses is growing exponentially. Human DNA undergoes three main levels of control. The first is replication where the genome is reproduced in […]

Characteristics of an Infrared, Slitless, Spectroscopic, Emission-Line Galaxy Survey

by

Jacob Peter Fugal and Dr. J. Ward Moody, Physics and Astronomy Cosmology has always attracted the minds of those who pursue the burning question of how the universe began. Since Edwin Hubble proved not only the existence of galaxies outside the Milky Way but also that the further away they are, the faster they are […]

Distribution of Isoforms of the Sodium Pump in Pregnancy-related Tissues: Changes for Women in Labor

by

David S. Faux and Dr. Steven W. Graves, Chemistry and Biochemistry The birth of a baby has always been regarded as a miracle. Even today the carefully orchestrated events that result in birth elude the outreaches of scientific research. Among the most important of these events are the contractions of the uterus termed labor. Several […]

Elements Regulating Excision of Chicken Cyclooxygenase-2 Intron 1

by

Nathan Evanson and Dr. Daniel L. Simmons, Chemistry and Biochemistry Cyclooxygenases (COXs) are enzymes that are responsible for the production of a potent class of biological signaling molecules called prostaglandins. Prostaglandins are involved in responses such as inflammation, contraction of smooth muscle, and regulation of water balance in the kidney. They are also found in […]

Spin Current: The Contribution of Spin to the Probability Current of Nonrelativistic Particles with Spin

by

Philip Du Toit and Dr. Jean-Francois Van Huele, Physics and Astronomy Introductory quantum mechanics texts seldom treat the quantum mechanical probability current for nonrelativistic particles with spin. The procedure for calculating probability current is most often presented in relation to particles described by the Schrödinger equation, that is particles without spin.1 In later chapters, after […]

Human-Robot Interface Design

by

Jacob W. Crandall and Dr. Michael A. Goodrich, Computer Science Over the last few years, there have been vast advancements in robot technology. These advancements have made robots more powerful. However, because of robot limitations, many interesting tasks will probably include humans and robots cooperating to achieve a shared goal. Lessons from process automation indicate […]

Electronic Control of the Photocycloaddition of Silyl Tethered Alkenes

by

Kari Cowdell and Dr. Steven A. Fleming, Chemistry and Biochemistry Solar energy is a major reason for the study of photochemistry. Photochemistry is the investigation of the interaction of organic compounds with light. The ability of plants and bacteria to harness the sun’s energy is an example of photochemistry. One area of photochemical research is […]

Preparation of Green Fluorescent Protein Constructs for the Determination of the Mechanism of the Excision of a Novel Intron

by

John Daniel Clinger and Dr. Daniel L. Simmons, Chemistry and Biochemistry Recent advances have greatly increased the utility of bioluminescence as a qualitative and quantitative tool in scientific research. The genes encoding fluorescent proteins in several organisms have been identified, cloned, modified, and inserted into several different vectors; thus allowing them to be used in […]

In Situ Ellipsometry of Surfaces in an Ultrahigh Vacuum Thin Film Deposition Chamber

by

Joseph S. Choi and Dr. David Allred, Physics and Astronomy As current microtechnology advances toward building nanosize components for computers and aerospace devices, oxidation of thin films can have dramatic effects on the electronic and optical properties of these devices. In order to understand optical properties of thin film materials and their oxides in a […]
